Seminars in Forest Genetics at Umeå
There are three seminars in forest genetics planned for the coming weeks by visitors from Faculty of Forestry, Czech University of Agriculture, Prague Czech Republic
Place: The seminar room of the department of forest genetics and plant physiology (floor 4 close to entrance on floor 2)
Milan Lstibureks Czech supervisor, Jaroslav Kobliha, will hold a seminar
"Forest tree breeding projects of the Department of Dendrology
and tree breeding at Faculty of Forestry, Czech University of
Agriculture in Prague".
Time: Wednesday, June 7 at 9.00
My comment: Dr Kobliha seems to have succeeded in getting offspring in crosses between sylvestris and contorta, that may be of interest to make questions on that point from some of you.
Wednesday 14th of June 9.00

Head of the Dept. of Dendrology and Tree Breeding
Kobliha and Chalupka will visit Uppsala June 16.
Barry Goldfarb
I have got the following information from Ulfstand Wennström: Vi har bjudit hit Barry Goldfarb från Dep. of Forestry, North Carolina State
University. Han är expert på rotning av tallsticklingar. För att så många som möjligt ska få del i hans kunskaper så kommer han att hålla ett seminarium på förmiddagen den 21/6 i sal Björken. Temat blir: "Rooting cuttings from P. elliottii (loblolly pine)". Barry Goldfarb will visit Uppsala also.
Quantitative genetics in breeding
There is a conference on quantitative genetics in breeding, more information on

Tim Mullin
Since 1994 TJ Mullin has been an important collaborator to our group. His support was instrumental to the PhD Forest Genetics thesis 1999 by Rosvall and Andersson as far as to many of the other studies of our group. He has been appointed director of a joint University - Industry Cooperative Breeding Program in South Eastern US. The breeding program supports a planting of around 1 billion Pinus taeda plants. He replaces Bob Weir, who retires. He takes up the new position at around this moment. In the same time he was appointed full professor at North Carolina State University in Raleigh. We give our congratulations to Tim to the appointment and hope that this will continue to strengthen ties and cooperation between Sweden and Raleigh.
Search for papers and references at the web
For those associated to SLU there is a service to find literature (citations).
This is the address of Web of Science:
http://isi.libris.kb.se/CIW.cgi
it is a useful way to find late relevant references, and I guess citations will be more recent thanks to similar services.
Journal citation report (see below) can be found at
http://jcrweb.com/
For these sites, however, authorisation is required, which SLU and some other institutions have, but SkogForsk probably has not.
Information and demo-versions can be found at
Information, which can be found at the site "Journal citation report" is shown below. Note that e.g. Forest Genetics is not covered in the data base, thus 50% of the journals dealing with our speciality (forest genetics) is not covered. For SJFR it seems to have established itself well in spite of its short life-time, my congratulations to those who have contributed to make it successful (among them Anders Ericsson, Gösta Eriksson and a lot of contributors and reviewers). I think it says more about differences between forest geneticists and plant physiologists than about the journals that Tree Physiology has four times higher "impact" than Silvae Genetica.

(handledare Alfred Szmidt, skoglig genetik Umeå) har bokat in disputation 8 Sept.Katsuhiko Takata
and Song Wan are visiting the genetics Umeå corridor for around a year. Darius Danusevicius (known to many of us) will visit us during JulyNext Nordic forest geneticist-breeder meeting will probably occur in Finland March 2001
New programs
I have constructed two new EXCEL-sheets concerned with questions like: how many sites?; over which range to use the same material?; what's the consequences for adaptation that we draw seed orchard parents from a range of sites?

Britta Danell, Gene Namkoong and Ron Sederoff are appointed as scientific experts to the evaluation committee and are now looking at the merits of the applicants.
Preliminary abstract to Milan's exjob
Much effort goes into the development of vegetative propagation using micropropagation and other methods. This work analyses the profitability of vegetative propagation in forest tree breeding exemplified by birch. Such analysis was done by comparisons built on published formulas, compiled in an Excel worksheet. The worksheet enables calculations in major breeding alternatives. Inputs used in this study are genetic variance components, cost components as well as number of parents, number and size of families, size of clones, number of selected families and genotypes within a family. Outputs are gain, status number, and total cost. Total investment, cost components (related to the additional genotypes and experimental plants) and heritability were found to be the most important factors affecting the efficiency of cloning in genetic testing. Cheap additional plants, high cost per additional genotype and low narrow-sense heritability make clonal option in testing more beneficial. Presence of dominance variance lowers the benefit marginally. When full-sib families are tested (and the best genotypes are later selected from the best-ranked families), each genotype can be multiplied by number of its clonal copies before the test is planted. This is highly beneficial for testing birch. Clonal test (for backward selection of the best founders) is better compared to half-sib progeny test in a wide range of conditions provided an efficient propagation technique is available. Micropropagation is mentioned as a possibility to establish birch clonal tests. One can use this work as an introductory manual for an analysis more in depth.
